The present invention relates to means for applying adhesive to stripsof material such as pipings utilized for ornamenting ladies shoes andother articles.

5 Pipings used for shoe ornamentation are usually initially secured inplace between portions of the shoe upper material by means of anadhesive in fluid or plastic condition. The application of the adhesiveto the piping has heretofore 10 been accomplished usually by immersing aroll or bunch of the piping in the adhesive or by applying the adhesivecoating to the piping by means of a brush. These methods areobjectionable because, among other things, the adhesive covers 15 theentire surface of the piping and. stains or discolors the latter,whereas it is necessary only to apply the adhesive to the part of thepiping which is not visible in the finished shoe or other article. Themain object of the present invention, therefore, is to obviate theobjections and disadvantages of the prior art methods of applyingadhesive tostrips of piping or similar material.

Piping used for ornamenting shoes is usually 25 positioned betweenportions of the shoe upper as, for example, between the vamp and thequarter, so that only a marginal edge portion of the piping is visiblein the finished shoe. Such pipings are usually of the beaded edge typeor of the type 30 which has a folded marginal edge portion which is theedge portion of the piping that is visible. As stated, it is unnecessaryto apply adhesive to the portion of the piping which will be visible inthe finished shoe; on the other hand, the ap- 35 plication of adhesiveto such visible portion of the piping is undesirable for the reasonshereinbefore mentioned. Accordingly, another object of the presentinvention is to provide means for applying adhesive to piping or similarmaterial in 40 such manner that a marginal edge portion thereof is freeof theadhesive, and a further object of the invention, in thisconnection, is to provide means for predetermining the width of thepiping to be coated with the adhesive and to prevent 45 the adhesivefrom reaching the portion of the piping which it is desired to be freeof the adhesive.

The adhesive usually employed for attaching pipings to shoe uppers is arubber cement, the characteristics of which are well known to thoseskilled in the art. One characteristic of such rubber cement is that itis deleteriously affected by exposure to the atmosphere. Another objectof the present invention, therefore, is to provide an adhesiveapplicator for use with rubber cement, constructed to greatly minimize,if not prevent, the exposure of the cement to the atmosphere prior tothe application of the cement to the material to be coated therewith.

A yet further object of the invention is generally to facilitate theapplication of an adhesive to piping and other strips of material.

The above objects of the invention and other objects ancillary theretoWill best be understood from the following description read inconnection with the accompanying drawings.

In the drawings:

Fig. 7 is a sectional View on the line 1-1 of Fig. 4.

Referring to the drawings in detail, the applicator comprises areceptacle having side walls ill, a bottom wall l2, a front wall It, anda rear wall 16. The receptacle is divided by means of a partition I 8into a supply compartment 20 and a distribution compartment 22. Thepartition I8 has an opening 24 through which the adhesive may pass fromthe supply compartment 20 to the distribution compartment 22. A slidingvalve or gate 26 is movably mounted'in guideways 28 secured to thepartition I8, and may be raised and lowered in said guideways to uncoverand cover said opening 24.

The supply compartment 2!! is provided with a cover 3|! which engages aninner peripheral flange 32 formed at' the upper edgesof the walls of thecompartment 20, and is seated on a gasket 34 to provide a substantiallyair-tight seal between the cover and said flange 32. Spring fingers 36are secured to the under-surface of the 'cover 30 adjacent the forwardedge thereof and are constructed and arranged to engage below the flange32 adjacent the partition l8, and thereby exert pressure on the cover 30to retain the latter in tight engagement with the gasket 34. The rearend of the cover is provided with a depending flange 38 5 which overliesthe upper end of the rear wall I6 and is secured to the latter by meansof. a screw 48 which passes through aligned screw-threaded apertures 42and 44 in said flange 38 and wall I6, respectively, thus securing thecover in position in fluid-tight engagement with the receptacle, and atthe same time facilitating removal of the cover. A tube 46 depends fromthe cover 38 into the compartment 28 and terminates at its lower end ata relatively short distance from the bottom wall I2 of said compartment.Said tube constitutes means to form a seal to regulate the flow of theadhesive from the inverted container 48 and also, prevents or greatlyminimizes the access of air to the adhesive in the compartment 28. Thecover 38 is provided with an upstanding flange 58 in alignment with theupper end of the tube 46. Said flange is provided with a plurality ofbayonet slots 52 which cooperate with projections on the adhesivecontainer 48 for obtaining a quick detachable connection between saidcontainer and the adhesive receptacle. The gasket 54 is seated withinthe flange 58 and is engaged by the mouth of the inverted container 48,forming a fluid-tight joint therewith.

A support 56 for the spool 58 on which the piping is wound is mounted onthe cover 38. Said support comprises arms 68 secured at their lower endswithin an opening 62 provided in the flange 58. The upper ends of saidarms have inturned end portions 64 which may engage the sides of thespool 58 or, as here shown, extend for a short distance into the hollowcylindrical portion 59 of said spool. A cover 18 for the distributioncompartment is pivotally connected to the partition I8 by means of ahinge 12.

The adhesive in the distribution compartment 22 is applied to the pipingthrough an opening 14 in the front wall I4 adjacent the bottom wall I2of the receptacle. A gate valve 16 for covering and uncovering saidopening is slidable on the inner. surface of said wall in guideways 18soldered or otherwise secured to the inner surface of the wall. Animportant feature of. the present invention resides in the provision ofmeans for guiding the piping for movement across said opening for theapplication of adhesive thereto. A block 88 having a groove 82 issecured in any suitable manner as by screws 84 to the wall I4 adjacentthe upper edge of the latter. Said groove 82 is closed by the underlyingsurface of the wall I4, forming a slot through which the piping P isthreaded for directing said piping toward the opening 14. Means areprovided for pressing a marginal edge portion of the piping against thewall I4 at one side of. the opening 14 as the piping is moved acrosssaid opening. Said pressing means comprises a member 86 provided with ahead 88 and a finger 98 arranged to bear on the piping. Said head 88 isprovided with a slot 92. A threaded lug 94 fixed to the block 88 extendsthrough the slot 92 in engagement with the opposite side edges of saidslot, permitting lateral adjustment of the presser member 86 in relationto the opening 14. A coiled compression spring 96 is disposed on the lug94 in position to bear on the opposed surfaces of the block 82 and thepresser head 88. A nut 98 is threaded on the lug 94 and bears on thehead 88 to secure the presser member 86 in adjusted position. Said nutalso constitutes means to regulate the pressure of the finger 98 on thepiping P, and for this purpose, cooperates with the head 88 and thespring 96 and, more particularly, with a flange I88 which bears on theblock 88 when the nut 98 is threaded down. The lower free end of thefinger 98 has an upwardly-curved portion I82 which overlies an inclinedledge I84 on the wall I4 adjacent the lower edge of the opening 14,forming a smooth passage for the piping as it is drawn across saidopening and beneath the presser member 86. The inclined ledge I84 alsoserves to remove excess adhesive from the surface of the piping asthelatter is drawn thereacross in engagement therewith.

The means for guiding the strip of piping across the opening 14 alsoincludes means for determining the width of the marginal edge of thepiping which is to be free of adhesive. Said means comprises a block I86slidably mounted on the wall I4 in guideways I88 soldered or otherwisesecured to said wall. Said block is provid-ed with a slot H8, and athreaded lug H2 is secured to the wall I4 and projects through said slotfor engagement by a threaded nut II4 which bears on the block 86 tosecure the latter in adjusted position. Said block is movable toward andaway from one side 15 of the opening 14. Another block II6, similar inall respects to the block H8, is also mounted on the front wall l4 andis movable toward and away from the opposite side edge 11 of the opening14. Said block H6 is provided with a slot H8 and may be secured inadjusted position by means of a nut I28 engageable with a threaded lugI22 fixed to the front wall I4 and arranged to project through the slotIIB.

As best shown in Fig. '1, the width of the marginal edge portion of thepiping P to be free of the adhesive is predetermined by positioning theblock I86 so that the edge I81 thereof is disposed at a definitedistance from the edge 15 of the opening 14. The presser 88 is adjustedlaterally of the opening so that one side edge of the presser finger 98abuts said edge I81 of the block I86. The other block H6 is adjusted sothat the opposite edge of the presser finger 98 abuts or is close to theadjacent edge of the block. Thus, in effect, a guide channel is formedby the confronting edges of the blocks, by the underlying portions ofthe wall I4 including the ledge I84, and by the overlying presser finger98. The pressure on the finger 98 is regulated by the nut 98 dependingupon the amount of adhesive desired on the portion of the piping to becoated therewith, less adhesive being applied to the piping as morepressure is exerted by the finger on the piping as it passes between thefinger and the ledge I84. The presser member bearing on the pipingcauses the marginal edge portion thereof, derlying portion of the wallI4 between the opening edge 15 and the block edge I81, to form a sealwhich prevents the adhesive from reaching said marginal edge portion ofthe piping,

while the remaining width of the piping between the opening edge 15 andthe edge of the piping removed therefrom is coated with the adhesive.

Thus, it is seen that the apparatus herein shown and described is welladapted to accomplish the several objects of the present invention. Itwill be understood, however, that certain changes in the constructionand arrangement of parts may be made and that certain features of theinvention may be used without others.
